Liquid container

ABSTRACT

A container comprises a first tubular body, a second tubular body disposed in the first tubular body, and a tubular cap slidably engaged with the first tubular body. The second tubular body has a chamber for containing a liquid and a neck portion protruding from the first tubular body. The neck portion has a surface at an end thereof puncturable to provide a discharge opening. The tubular cap has a first end, a second end, and a needle pin disposed inside of the tubular cap and mounted on an inner wall of the tubular cap at the first end thereof. The tubular cap is slidable on the first tubular body between a first position in which the needle pin is spaced from the surface of the neck portion of the second tubular body, and a second position in which the needle pin punctures the surface of the neck portion to provide the discharge opening. A first air-tight seal maintains the interior of the tubular cap in a hermetically sealed state when the tubular cap is in the first position. A second air-tight seal maintains the interior of the tubular cap in a hermetically sealed state when the tubular cap is in the second position.

TECHNICAL FIELD

The present invention relates to a liquid container for containing aliquid which must not be exposed to the moisture, since such liquid issolidified upon absorbing the moisture in the air and becomes no longerusable, as represented by a cyanoacrylate-type instantaneous adhesiveagent, and a liquid which must not be dried, and thus solidified, andwhich requires time before it can be used again, as represented by arectifying (retouching) liquid.

BACKGROUND ART

A known container of this type, for example, a container containing aninstantaneous adhesive agent has a structure in which the discharge holeis closed by interposing a stopper member between a cap and a containerbody before it is used by a user, the stopper member is removed when thecontainer is to be used by the user, and the discharge hole is formed bybeing pierced by a needle pin projected at the center of the inner topof the cap (Japanese Patent Laid-Open No. 6-135450/1994).

As a container for containing a liquid which becomes no longer usableupon absorbing the moisture in the air as represented by thecyanoacrylate-type instantaneous adhesive agent, furthermore, there hasbeen known a one-push-squeeze-type double-structured adhesive containercomprising a flexible inner container filled with an adhesive solution;a squeeze-type flexible outer case body for hermetically accommodatingsaid flexible inner container with its outlet at the upper end beingoutwardly protruded and forming a closed space inside therein so as tobe pushed from the outer side; and a cap for wrapping the outlet at thetip of said flexible inner container and the upper end of said flexibleouter case body and detachably having a piercing member with a pin in arecessed portion formed at a suitable position thereof, wherein theflexible outer case body has a drying agent-containing chamber in whichis hermetically contained a drying agent between the bottom end thereofand the bottom end of said flexible inner container as disclosed inJapanese Patent Laid-Open No. 5-294371/1993.

However, the container disclosed in Japanese Patent Laid-Open No.6-135450/1994 has a problem in regard to the handling since the stoppermember must be removed by the user prior to using the container.

According to the container disclosed in Japanese Patent Laid-Open No.5-294371/1993, a drying agent-containing chamber is provided between thebottom end of the flexible outer case body and the bottom end of theflexible inner container, and a drying agent is sealed in the dryingagent-containing chamber. However, the drying agent is placed in aclosed space formed between the flexible outer case body and theflexible inner container, and the effect of the drying agent is limitedwithin a closed space only but does not extend to the inside of the cap.Though the outlet at the tip of the flexible inner container has beenclosed before it is used by the user, the container, in general, hasbeen made of a synthetic resin which permits the air to permeate to someextent. Therefore, the instantaneous adhesive agent inside absorbs themoisture contained in the air that has permeated therethrough, wherebythe liquid is solidified and becomes no longer usable. In other words,the liquid tends to be solidified near the liquid discharge hole. Thisproblem is caused even after the user started to use the container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention will now be described in detail with reference to theaccompanying drawings.

FIGS. 1 to 3 illustrate a first embodiment of the present invention. Acontainer body 1 contains therein a liquid-containing chamber 2 forcontaining a liquid which is solidified upon absorbing the moisture inthe air and becomes no longer usable as represented by acyanoacrylate-type instantaneous adhesive agent, or a liquid that mustnot be dried since it is solidified upon drying and requires a timebefore it can be used again as represented by a rectifying liquid. Thefront part of the liquid-containing chamber 2 comprises a neck portion 4having, at the tip thereof, a discharge opening or hole 3. The dischargehole 3 has been closed in FIG. 1 but is pierced by a needle pin 18planted on the inner top panel of a cap 17 when the cap is moved, asshown in FIG. 2, in a direction of the discharge hole to use thecontainer. The container body 1 is made of polyethylene, polypropylene,polyethylene terephthalate, nylon or a like material. The container body1 is at least partly constituted by a synthetic resin having an elasticrestoring property so that, when it is depressed at least partly, theliquid-containing chamber 2 is pressurized and the liquid is forced tothe discharge hole 3. The neck portion 4 may be molded as a unitarystructure or may be separately molded and may then be united together.

An outer container body 5 has a small-diameter portion 6 at a tipthereof, a tail plug 7 at a rear portion thereof, and contains thecontainer body 1. An annular bottom protuberance 8 is formed on the tailplug 7 of the outer container body 5, and a size-adjusting rib 9 isformed inside the annular bottom protuberance 8.

Space 11 is formed between the container body 1 and the outer containerbody 5.

Reference numeral 14 denotes a first air-tight receiving portion, and 15denotes a second air-tight receiving portion, which will be describedpresently in detail. Reference numeral 16 denotes a threaded portionformed on the outer periphery of the small-diameter portion 6 of theouter container body 5.

Like the container body 1, the outer container body 5 is made ofpolyethylene, polypropylene, polyethylene terephthalate, nylon or a likematerial. The outer container body 5 is at least partly made of asynthetic resin having an elastic restoring property so that, when it isat least partly depressed, the liquid-containing chamber 2 ispressurized through the container body 1 and the liquid is forced to thedischarge hole 3.

The cap 17 made of a synthetic resin has the needle pin 18 planted onthe inner top panel thereof and has a stopper portion 19 (see FIG. 3)formed at an open end thereof integrally therewith or as a separate body(integrally therewith in FIG. 3), the stopper portion 19 being allowedto move in the direction of the discharge hole 3 of the container body 1so as to be removed, thereby defining a break-away portion. The cap 17is fastened to the small-diameter portion 6 of the outer container body5 being allowed to move. In this embodiment, the fastening isaccomplished by forming a threaded portion 20 in the cap, and fittingthe threaded portion 20 to the threaded portion 16 formed on the outerperiphery of the small-diameter portion 6 of the outer container body 5.The needle pin 18 may be made of a synthetic resin and may be moldedtogether with the cap 17 as a unitary structure.

Reference numeral 21 denotes a first air-tight press-contacted portion,and 22 denotes a second air-tight press-contacted portion.

In the above construction, a first air-tight portion or seal (airshut-off portion) 23 is formed by the first air-tight receiving portion14 and the first air-tight press-contact portion 21. Communication withthe external air in the cap 17 is shut-off until the container is usedby a user, and the inside of the cap 17 is maintained in a hermeticallysealed state. A second air-tight portion or seal (air shut-off portion)24 is formed by the second air-tight receiving portion 15 and the secondair-tight press-contact portion 22. Communication with the external airin the cap 17 is shut off when the container is stored after use, andthe inside of the cap 17 is maintained in a hermetically sealed state.Described below is the shape of the stopper portion 19 of the cap 17 andhow to remove it according to the embodiment. In the embodiment, thestopper portion 19 is integrally molded like a ring via a thin portion19a. When the cap 17 is moved in the direction of the container body 1,the thin portion 19a is cut. When the cap 17 is further moved in thedirection of the container body 1, the needle pin 18 pierces thedischarge hole 3 that had been closed due to this motion (see FIG. 2).Thereafter, the stopper portion 19 that is cut is pulled up and isremoved.

The shape of the stopper portion and the method of removal can berealized in various other ways. As shown in, for example, FIG. 4, thestopper portion 19 may be constituted using three or more ribs (fourribs in FIG. 4). As shown in FIG. 5, furthermore, the stopper portion 19may be constituted by a C-ring which is separate from the cap 17 andwhich outwardly opens when the cap 17 is moved in the direction of thecontainer body 1. In this case, the cap 17 is moved to expand the C-ringwhich is then torn off. As a means for outwardly expanding the C-ringwhich is the stopper portion 19 when the cap 17 is moved in thedirection of the container body 1, tapered protuberances 17a are formedon the outer periphery of the cap 17 as shown in FIG. 5. When the cap 17is moved in the direction of the container body 1, the C-ring isexpanded due to the tapered protuberances 17a. In effect, the lower endof the cap 17 and(or) the upper end of the C-ring is tapered in order toconvert the force in the lengthwise direction of the cap 17 into a forcein the circumferential direction. In FIG. 5, the cap 17 and the stopperportion 19 may appear as a unitary structure. In practice, however, theyare formed separately from each other. It is, of course, allowable toform the cap 17 and the stopper portion 19 as a unitary structure thoughthe structure requires a complicated method of production.

FIGS. 6 to 9 illustrate a second embodiment of the present invention.

In the first embodiment, the stopper portion 19 is formed integrallywith, or separately from, the open end of the cap 17. The secondembodiment, however, is different from the first embodiment in that nostopper portion is formed and the cap 17 is moved by being pushed, whilein the first embodiment it is accomplished by fitting of the threadedportion 16 of the outer container body 5 to the threaded portion 20formed on the inner surface of the cap 17, and is different in the firstand second air-tight portions. In the figures of the drawing, likeportions are assigned identical reference numerals.

In the second embodiment of FIGS. 6 to 9, no stopper portion is formed.Before the container is used by a user, a gap is maintained between therear end of the cap 17 and a shoulder step portion 5a of the outercontainer body 5, so that the tip of the needle pin 18 of the cap 17will not come into contact with the discharge hole 3. Moreover, on thesmall-diameter portion 6 of the outer container body 5 is formed a firstair-tight receiving portion 14 in a manner that its front protrudedportion is tilted, a first air-tight press-contacted portion 21 isformed on the inner surface of the cap 17 in a manner that its rearprotruded portion is tilted, and a first air-tight portion 23 isconstituted by the engagement of the two.

After the container is used by pushing the cap 17 (discharge hole 3 ispierced by the needle pin 18), the protruded portion on the innersurface of the cap 17 gets over the protruded portion on thesmall-diameter portion 6 of the outer container body 5. In other words,the rear tilted portion of the protrusion formed on the small-diameterportion 6 of the outer container body 5 forms a second air-tightreceiving portion 15, the front tilted portion of the protrusion formedon the inner surface of the cap 17 forms a second air-tightpress-contact portion 22, and a second air-tight portion 24 is formed bythe engagement of the two.

In this embodiment, a protruded portion is formed on the small-diameterportion 6 of the outer container body 5 and on the inner surface of thecap 17, and the engaging positions of these protruded portions arechanged to form the first and second air-tight portions 23 and 24. Theair-tight portions, however, can be constituted in a variety of otherways. As shown in, for example, FIGS. 8 and 9, two dents or recesses areformed in the small-diameter portion 6 of the outer container body 5,the front dent is used as the first air-tight receiving portion 14 andthe rear dent is used as the second air-tight receiving portion 15.Moreover, a protruded portion is formed on the inner surface of the cap17 and is used as the first or the second air-tight press-contactportion 21 or 22. The first air-tight portion 23 is formed by the firstair-tight receiving portion 14 and the first air-tight press-contactportion 21, and the second air-tight portion 24 is formed by the secondair-tight receiving portion 15 and the second air-tight press-contactportion 22.

In the second embodiment, the first and second air-tight portions areformed by the engagement of the protruded portion formed on thesmall-diameter portion 6 of the outer container body 5 and the protrudedportion formed on the inner surface of the cap 17. The two protrudedportions, however, may simply be used as a hook means between the two,and the air-tight portions may be constituted by the same portions asthose of the first embodiment.

FIGS. 10 and 11 illustrate a third embodiment of the present inventionwhich corresponds to the first embodiment of FIGS. 1 and 2. The samemembers and portions as those of the first embodiment are denoted by thesame reference numerals as those of the first embodiment.

This embodiment is different from the first embodiment in that a dryingagent 10 is placed between the size-adjusting rib 9 inside the annularbottom protuberance 8 and the bottom of the container body 1, and thatspace 11 formed between the container body 1 and the outer containerbody 5 is connected with the inside of the cap 17.

The drying agent 10 may be placed in space 11 which is connected withthe inside of the cap 17. In this embodiment, a flange hole 12 is formedin the front end of the small-diameter portion 6 which is in contactwith the container body 1, and a groove 13 is formed in thesmall-diameter portion 6. However, a variety of known means can beemployed which permit the flow of the air, such as forming ribs, etc.Even in the first embodiment, the cap 17 is so drawn on the drawing thatthe inside thereof is connected with space 11 formed between thecontainer body 1 and the outer container body 5. In the firstembodiment, however, communication of the inside of the cap 17 withspace is not an essential requirement.

FIGS. 12 and 13 illustrate a fourth embodiment of the present inventionwhich corresponds to the second embodiment of FIGS. 6 and 7. The samemembers and portions of the second embodiment are denoted by the samereference numerals as those of the second embodiment.

The fourth embodiment is different from the second embodiment in thesame points that are making the third embodiment different from thefirst embodiment.

According to the present invention a, space connected with the inside ofthe cap is formed between the container body and the outer containerbody, the first air-tight portion for shutting off the external air isformed by the inner surface of the cap and the outer container body in astate where the needle pin, before the container is used, is kept awayfrom the discharge hole, and the second air-tight portion for shuttingoff the external air is formed by the inner surface of the cap and theouter container body in a state where the discharge hole is pierced bythe needle pin when the container is used. Therefore, the discharge holeis easily pierced by the needle pin by moving the cap in the directionof the discharge hole of the container body. Besides, the drying agentplaced in space between the container body 1 and the outer containerbody 5 exhibits its effect as far as the inside of the cap 17, making itpossible to prevent the liquid from solidifying near the discharge hole3 at the tip of the neck portion 4.
